Abstract

Un motore elettrico sincrono è formato da un pacco lamellare statorico (2) provvisto di almeno un avvolgimento elettrico (6, 6') e da un rotore (3) in materiale ad elevata retentività magnetica; i lamierini (4) del pacco (2) sono disposti parallelamente all'asse del rotore (Z) per limitare l'ingombro trasversale del motore (1). Il pacco lamellare (2) ha sostanzialmente forma di U con tronchi rettilinei (5, 5') sui quali sono previsti avvolgimenti (6, 6') con assi delle spire sostanzialmente paralleli all'asse (Z) del rotore (3); i lamierini (4) hanno, in corrispondenza dei tronchi (5, 5'), altezze differenziate lungo una direzione trasversale (X) rispetto all'asse (Z) del rotore (3). Il pacco lamellare (2) con i suoi avvolgimenti è annegato in una matrice di resina (12) isolante, a sua volta ermeticamente racchiuso entro un involucro (11) sostanzialmente rigido di materiale dielettrico formando una capsula modulare sigillata. Tale capsula può essere accoppiata ad unità rotoriche di diversa tipologia per formare pompe immergibili.A synchronous electric motor is formed by a stator lamellar pack (2) provided with at least one electric winding (6, 6 ') and by a rotor (3) in material with high magnetic retentivity; the laminations (4) of the pack (2) are arranged parallel to the axis of the rotor (Z) to limit the transverse dimensions of the motor (1). The lamellar pack (2) is substantially U-shaped with straight trunks (5, 5 ') on which windings (6, 6') are provided with turns axes substantially parallel to the axis (Z) of the rotor (3); the laminations (4) have, at the trunks (5, 5 '), differentiated heights along a transverse direction (X) with respect to the axis (Z) of the rotor (3). The lamellar pack (2) with its windings is embedded in an insulating resin matrix (12), in turn hermetically enclosed within a substantially rigid envelope (11) of dielectric material forming a sealed modular capsule. This capsule can be coupled to different types of rotor units to form submersible pumps.
